Abstract (en)

Disclosed herein is a method of welding superalloy articles. A buttered layer (14) is attached to a first article (10) formed from a superalloy (12). A buttered layer (14) is attached to a second article (10) formed from a superalloy (12). Residual stresses are relieved between the buttered layer and the superalloy. Matching faying surfaces (16) are established at the buttered layers of the articles. And, the faying surfaces of the articles are welded together to form a welded assembly, wherein after welding, a heat affected zone (20) is within the buttered layers.
